Description

Description: TECHNICAL FIELD The present invention relates to a cartridge having a photosensitive recording medium therein.

[Prior Art] Conventionally, as the cartridge as described above, there is known one in which a photosensitive pressure-sensitive paper used in a photosensitive pressure-sensitive copying machine is wound. An opening is provided in this type of cartridge, and after being attached to the light and pressure sensitive copying machine, the light and pressure sensitive paper is pulled out from the opening and used.

When storing this cartridge, in order to prevent the photosensitive pressure-sensitive paper that is not used from being exposed to light from the opening, the leader portion attached to the leading end of the photosensitive pressure-sensitive paper is slightly exposed, The opening was covered with a light shielding member.

[Problems to be Solved by the Invention] However, in an apparatus such as a copying machine using the cartridge as described above, in order to remove the slack of the photosensitive pressure-sensitive paper,
Back tension is applied to the winding shaft of the cartridge. Therefore, after mounting the cartridge in the above device,
When trying to remove the light shielding member, it is necessary to hold the exposed portion by hand, and the operability is deteriorated. If the exposed portion is accidentally released, the leader portion is pulled in by the back tension, and it is necessary to disassemble the cartridge in a dark room or the like in order to use the photosensitive pressure-sensitive paper in the cartridge. Yes, I could not deal with general users.

The present invention has been made to solve the above problems, and an object thereof is to improve operability in processing such as mounting of a cartridge and setting of a photosensitive recording medium.

[Means for Solving the Problems] In order to achieve the above object, the cartridge of the present invention comprises:
It is characterized in that it has a light-shielding member that can cover the opening of the cartridge case from the outside, and that it also has a holding member that holds the tip of the long photosensitive recording medium.

[Operation] In the cartridge of the present invention having the above configuration, the photosensitive recording medium is stored in a state of being drawn into the cartridge case. At this time, since the light shielding member covers the opening, light does not leak into the cartridge case.

Also, as described above, for example, even in the case of being mounted in a device with a back tension, until the holding member is removed, even if the hand is accidentally released, the light shielding member is locked at the opening portion, It is not drawn inside. Therefore, if the holding means is removed after the front end of the photosensitive recording medium is held by the openable and closable feed roller or the like, the photosensitive recording medium will not be drawn into the cartridge case.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

A photosensitive pressure-sensitive paper, which is a photosensitive recording medium, is wound around a shaft 12 installed in a cartridge case 11 shown in FIG. A leader portion 13 is attached to the front end of the light and pressure sensitive paper, and the front end is exposed to the outside through an opening 11a provided in the cartridge case 11. A holding portion 14 as a holding member is attached to the exposed leader portion 13, as shown in FIG.

Next, the holding portion 14 will be described with reference to FIG. As shown in the figure, the holding portion 14 has a locking member 21. The locking member 21 is bent substantially at the center and sandwiches the leader portion 13. (However, in the figure, it is shown open to explain the shape). The upper plate-like portion 21a of the locking member 21 is provided with two protrusions 22a and 22b, and the lower plate-like body 21b, which is in contact with the protrusions 22a and 22b in the folded state, has Holes 23a and 23b that engage with the protrusions are provided. The protrusions 22a and 22b pass through two through holes 13a and 13b provided in the
It engages with a and 23b and holds the leader portion 13.

Further, a spherical body 24 is provided on the upper plate-like body 21a, and at a position of the lower plate-like body 21b which can abut on the spherical body 24, the radius is slightly smaller than the radius of the spherical body 24. A triangular hole 25 having an inscribed circle of radius is provided. When the locking member 21 is folded back, overlapped and pressed, the spherical body 24 enters into the hole 25 and is locked.

Light-shielding plates 26a and 26b are attached to the upper and lower plate-like members 21a and 21b. Each of the light shielding plates 26a and 26b constitutes a light shielding member, and when the locking member 21 is folded and folded, it becomes a single plate-shaped light shielding wall. In this state, the light shielding plate 26
The light shielding wall formed by a and 26b is the cartridge 11
The opening 11a is wider than the opening 11a, and the opening 11a can be completely covered.
It serves to lock the leader portion 13 urged to be drawn into the inside. This claw plate 26b has two claws 2
7a and 27b are provided to facilitate locking of the light shielding wall to the opening 11a.

As shown in the figure, the light shielding plates 26a and 26b are provided so that the bent portion of the locking member 21 projects outward, and the user can operate by holding the projecting portion 21c. You can Each plate-like body 21a, 21b in this protruding portion 21c,
Protrusions 29 corresponding to the holes 28a and 28b and the operating member, respectively.
a and 29b are provided. The projections 29a, 29b project through the holes 28b, 28a of the other plate. These projections 29a and 29b are adjacent to each other, and the user can easily open the engaged locking portion in a folded state by pushing each projection with the thumb and the index finger so as to press them.

The present cartridge configured as described above has the shaft 12
Is rotated so that the leader portion 13 is completely retracted into the cartridge case 11 and stored. In this state, the opening 11a is covered by the light-shielding wall constituted by the light-shielding plates 26a and 26b, so that light leaks into the inside and the unused light-sensitive pressure-sensitive paper is not exposed to the light. .

When this cartridge is mounted in a device such as a copying machine or an image forming device, the shaft 12 applies a bias for back tension from the device side, and tries to wind the leader portion 13 inside. However, in this cartridge, the light shielding plates 26a, 26b and 27
Since it is locked by a, 27b, etc., it is not caught inside. The user holds the portion 21c of the locking member 21 protruding from the light shielding plates 26a, 26b from the cartridge in this state, pulls out the leader portion 13, and sets it in the apparatus. Then, after securely holding the leader portion 13 by, for example, a pair of rollers that can be freely opened and closed, the locking portion 21 is opened by pressing the protruding portions 29a and 29b with fingers to open the locking portion 21.
Remove book holder 14 from 13.

In this way, the photosensitive paper can be easily set in the device, and it is not necessary to erroneously pull the leader portion 13 into the cartridge case 11.

The present invention is not limited to the above embodiment,
Various modifications are possible.

[Effect of the Invention] As is clear from the above description, in the cartridge of the present invention, there is no fear that the leading end of the photosensitive recording medium is accidentally pulled into the cartridge case, and the operability for mounting in the apparatus is improved. Increase.
