Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention comprises a side fence that is movable according to the width of a stored stack of transfer paper, and a corner claw that is rotatably provided on the leading end side of the side fence in the transfer paper conveyance direction. The present invention relates to a transfer paper storage device having:

2. Description of the Related Art FIG. 6 is a longitudinal cross-sectional view of the main parts of a conventional transfer paper storage device. In the figure, 1 is the main body of the device, 2
3 is a side fence that can be moved according to the width of the transfer paper S.
4 is a bottom plate on which the transfer paper S is placed; 4 is a corner claw that is partially sandwiched between the tips of the side fences 2 and rotatably supported on a fulcrum 2b; and 4a is provided at the tip of the corner claw 4. The upright piece 5 is a compression coil spring interposed between the bottom surface 1a of the device main body 1 and the bottom plate 3.

The bottom plate 3 is urged upward by a coil spring 5, and the uppermost sheet of transfer paper S placed on the bottom plate 3 pushes the corner claws 4 upward slightly. At this time, in order to regulate the transfer paper S (top paper) to the paper feeding position,
The corner pawl 4 is formed with a retaining portion 4b that engages with the bottom surface 1a and prevents it from coming off upward.

[Problem to be solved by the invention] By the way, the device main body 1
When attaching or detaching the transfer paper, the transfer paper is moved perpendicularly to the conveyance direction. At this time, the transfer paper S pushes the side fence 2 outward due to its inertial force. Then, depending on the mounting structure of the side fence 2, the side fence 2 may tilt outward, thereby causing the corner claw 4 to come off the transfer paper S.

[0005]Furthermore, the bottom plate 3 is in a lowered state when replenishing transfer paper, and in the case of an apparatus having a mechanism in which the bottom plate 3 is raised by the operation of storing the main body 1 in the machine, the bottom plate 3 is raised rapidly. Therefore, due to the vibration, the corner pawl 4
This causes a problem in that the transfer paper S is pushed apart and comes off from the transfer paper S.

The present invention has been made based on this background, and provides a transfer paper storage device that eliminates the drawbacks of the conventional devices and prevents corner claws from coming off the transfer paper when the device is attached or detached. The purpose is to

[0007]

[Means for Solving the Problems] The above object is to provide a side fence that is movable according to the width of a stack of transfer paper stored therein, a side fence that is rotatably provided on the front end side of the side fence in the transfer paper conveyance direction, and a This is achieved by providing a transfer paper storage device having corner claws for regulating the paper bundle to the paper feeding position, including movement regulating means for regulating the movement of the corner claws in the width direction of the transfer paper. In this case, the movement restricting means is specifically a protrusion formed on the upright piece of the corner claw, an engaging piece formed on the side surface of the paper feed side of the apparatus main body that engages with the protrusion, or a groove. Consists of.

[0008]

[Operation] The protrusion provided on the corner claw engages with the locking piece or groove provided on the main body of the device, and when the side fence is tilted, the corner claw is supported by the protrusion. , prevented from moving outward.

[0009]

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. FIG. 2 is a front view of the corner pawl 4. A protrusion 4c is formed on the upright piece 4a of the corner pawl 4.

FIG. 3 is a vertical cross-sectional view of a main part of the apparatus main body 1, and FIG. 4 is a perspective view of the apparatus main body 1. A side surface of the apparatus main body 1 on the paper feeding side is provided with a protrusion 4c at a position where it engages with the protrusion 4c.
The engagement piece 1b is formed so as to be on the outside. The engaging pieces 1b are provided at two locations, for example, as shown in FIG. 4 depending on the width of the transfer paper S. Note that in FIG. 4, arrow d indicates the direction in which the device main body 1 is attached and detached.

Furthermore, the side fence 2 is moved every time the width of the transfer paper S changes. If a rack and gears are used to move the side fence 2, the projections 4c of the corner claws 4 should be engaged with the engagement pieces 1b on the device main body 1 only when the bottom plate 3 is raised. The shape of the joint piece 1b is determined.

FIG. 1 is a plan view of essential parts of a transfer paper storage device according to an embodiment, showing a state in which the corner claw 4 shown in FIG. 2 is assembled to the main body 1 of the device shown in FIGS. 3 and 4. . The corner claw 4 shown in FIGS. 1 and 2 is located at the back of the machine, and has an outer engagement piece 1b and a protrusion 4 for the wide transfer paper S.
Even if the side fence 2 is tilted due to the force in the direction indicated by the arrow f in the figure being applied by the engagement of the corner claws 4c, the corner claws 4 will not move outward because they are supported by the projections 4c. Therefore, it does not come off from the transfer paper S.

FIG. 5 is a plan view of essential parts of a transfer paper storage device according to another embodiment. In this embodiment, instead of the engagement piece 1b, a groove 1c into which a protrusion 4c is fitted is formed on the device main body 1 side. In this embodiment as well, similarly to the embodiment shown in FIG. 1, movement of the corner pawl 4 is prevented by engagement between the protrusion 4c and the groove 1c. In addition, the bottom plate 3
The mechanism for preventing the corner pawls 4 from coming off the transfer paper S due to vibrations caused by the rise of the transfer paper S can be constructed in the same way even when the direction in which the transfer paper storage device is attached and removed is the same as the direction in which the transfer paper S passes.

[0014]

[Effect of the invention] As explained above, claims 1 to 5
According to the invention described, the protrusion provided on the corner claw engages with the locking piece or groove provided on the main body of the device, so even if the side fence is tilted, the corner claw will not engage with the protrusion. Since it is supported by the support and prevented from moving outwards, reliable paper feeding is always possible.
