Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a form paper storage device (hereinafter referred to as a cassette for convenience) that is detachably attached to a printing device.

Conventionally, information processing machines (such as billing machines,
(accounting machines, electronic calculators, etc.), when setting form sheets with different formats, paper sizes, printing information, etc., into the printing device, the form sheets must be manually set into the printing device each time, and then tabulation and line feed returns are performed. width,
It was troublesome to select the program by specifying the timing margin position and the like.

SUMMARY OF THE INVENTION An object of the present invention is to provide a paper storage system in which, when a cassette is attached to a printing device, the position of the paper such as form paper stored therein can be adjusted according to the width of the paper, and information related to printing can be specified. The purpose is to provide equipment. The present invention will be explained below with reference to the illustrated embodiments.

FIG. 1 shows an example of paper using foam paper, and in the same figure, the base of a lid 2 is attached to one end of a box-shaped cassette 1 with a hinge (not shown). The surface of this lid 2 (the back side in the figure)
A paper stopper 3 is fixedly installed. Inside the cassette 1, folded form paper (form paper with continuous holes) (not shown) is stored. A platen 7 is provided at the left end of both side plates 5 and 6 forming the cassette 1.
Shafts 8 and 9 to which are fixed are rotatably mounted, respectively. The ends of both shafts 8 and 9 are notched in a semicircular shape, and can be attached to and detached from the shaft of the printing device 11.
This arrangement allows the shafts 8, 9 to engage the shafts of the printing device when the cassette is installed. Said side plates 5, 6
Hooks 5a and 6a are respectively formed at the left end in FIG. An instruction device 12 fixed to the left end of the cassette 1 gives commands to the printing device 11, and its function will be described later. A pair of guide plates 14 and 15 whose positions are adjusted along long holes 13a and 13b bored in the cover 13 are respectively attached to the cover 13 whose ends are fixed to the side plates 5 and 6, respectively. The guide plates 14 and 15 guide both side edges of the form paper 4 by moving in the width direction according to the width of the form paper 4 to adjust the position thereof. cover 13
A pair of sprockets 16 and 17 whose claws protrude beyond the surfaces of the sprockets 16 and 17 are respectively fixed to shafts 18 which are pivotally attached to the side plates 5 and 6. A drive gear 19 is fixed to the end of the drive gear 19, and this drive gear 19 meshes with the gear of one drive part of the printing device. The rod-shaped paper guide member 21 is supported by attaching its ends to arm members 22 and 23 fixed to the side plates 5 and 6, respectively, and guides the form paper 4 onto the sprockets 16 and 17. It has the effect of keeping it in constant contact with the target. FIG. 2 shows an example of the indicating device 12, and the front side of the device 12 is provided with slit groups A and B at the top and bottom, respectively.
It consists of slits 51 and 52 corresponding to the character spacing, respectively.

In FIG. 3, chips 53 and 54 are inserted into appropriate slits 52 of slit group B, and a removable fixing rod 55 is attached to the indicating device 12 as shown in FIG.
Each chip 53, 54 and a plurality of similar chips are held in the indicating device 12 by being inserted into holes drilled in the chips 3, 54. A chip 56 is also inserted into the upper slit 51 as shown in FIG. 4, and is held by a fixing rod 57. The chips 54, 56, etc. inserted into these slits are read by a sensor (not shown) provided in the printing device 11 when the force set 1 is attached to the printing device 11. By reading the shape of the protruding side edge X of each chip 54 and its insertion position, various fingers ◆ are given to the sensor from the indicating device 12. In Figure 1, when attaching the form paper to force set 1,
After passing the leading edge of the paper under the platen 7 and folding it back, feed wheels (not shown) bored along both side edges of the paper are fitted into the sprockets 16 and 17, respectively, and then This is done by inserting the tip end under the guide member 21.

The shafts 8 and 9 of the platen 7 are respectively connected to the main shafts of the printing device 11 as described above when the force set is installed in the printing device, and the drive gear 19 of the force set 1 meshes with the printing device idle gear. , the platen drive section of the printing device and the form paper drive section of the six-force set 1 are connected. By attaching the force set 1 to the printing device, the indicating device 12 of the force set 1 and a sensor (not shown) provided on the printing device are functionally coupled, and both of them are connected. Identification of information is carried out through collaboration between departments. Instructing device 1
2, in addition to the mechanical means of detecting the chip with a sensor as shown in FIG. 3, optical or electronic means may be appropriately selected and used. The instruction device 12 stores various instructions to the printing device 11 programmed in advance. Examples of the instruction contents include tab position specification, line feed and line break destination position specification, line feed width specification, and start of printing. season. This includes specifying the switching of the printer button, specifying the program address and download destination on the printing device side, and opening and closing the power supply on the printing device 11 side, etc. 6 All of these instruction contents are set in relation to the form paper. In FIG. 3, chips related to character positions among the above-mentioned instruction contents are selected and inserted into the slits in section A, and chips related to other instructions are selected and inserted into the slits in section B. According to the present invention, when loading form paper into the paper storage device, the paper is guided with both side edges of the paper always adjusted in position, regardless of the type of paper. It is now possible to load form paper into the force set, and the information instructions to the printing device that are set in relation to the form paper stored in the force set can be transmitted to the printing device when the force set is installed. At the point of time, the settings can be made with reference to the regulations of the card board, thereby eliminating the need to identify the contents of the cassette after the force set is attached and to set the drive control of the printing device.
