1 is a perspective view showing a printing machine to which the present invention is applied.

As shown in the figure, a paper storage case 21 is provided to be able to enter and exit the main body 11 of the printer 10.

In the paper storage case 21, it is possible to provide the paper size information stored therein into the system as a signal of a predetermined form, and its cross-sectional view in FIG. 2 is an exploded perspective view partially extracting some elements in FIG. Is shown.

Referring to the drawings, the paper container 20 is provided in the paper storage space provided in the paper storage case 21, the control plate 22 is provided to be linearly movable in one direction to regulate the outside of the received paper.

The regulating plate 22 is installed to guide the linear movement, to engage the linear sliding movement of a plurality of sliding guide projections 23 provided on the bottom surface to adjust the unit movement distance and to support with a predetermined engagement force. The restricting plate 22 adjusts its linear movement distance by the integral multiple of the length of one guide protrusion 23 with respect to the unit length. Sliding guide member different from the sliding guide protrusion 23 so as to regulate the regulation plate 22 by the engaging force for each position corresponding to the usable paper size of the regulation position of the regulation plate 22 (not shown) ) May be provided.

In the rear center portion of the paper storage case 21, there is provided a rotating plate 32 rotatably installed around the rotating shaft 31 fixed to the case 21.

As a linear-rotational motion converting means for rotating the rotating plate 32 in association with the linear movement of the regulating plate 22, one end thereof is coupled to one side of the rotating shaft 31 to wind the rotating plate 32 to a certain portion. In order to prevent the wire 34 from loosely loosening irrespective of the linearly moving position of the regulating plate 22 and the wire 34 which extends to the opposite side of the paper regulating surface of the regulating plate 22, the rotating plate 32 is provided. Roll springs (see Fig. 4, 33) are provided at both ends of which are coupled between the rotating plate 32 and the rotating shaft 31 to provide a restoring force to the rotational position set for the rotation of.

In addition to the roll spring 33, a rubber band may be wound between the rotary shaft 31 and the rotary plate 32 to provide a restoring force for rotation from the set rotational position of the rotary plate 32, for example.

Here, the roll spring generated by the rotation of the rotating plate 32 corresponding to the linear movement completion position of the regulating plate 22 adjusted by the user from the side wall 21a of the paper storage case 21 to the edge of the loaded paper ( The restoring force of 33 is determined so as to tension the wire 34 with a force such that the regulating plate 22 does not deviate from the completed position.

The rotary rollers 35 assist the sliding movement of the wire 35.

In the paper storage case 21 of the opposing surfaces of the rotating plate 32, a selectable pin member 40 provided with a plurality of protruding pins 41 to 44 is in contact with the main body 11 of the printer 10 as an interference switch. The switches 51 to 54 are provided.

Selective pin member 40 is fixed to the paper storage case 21, the pin guide member so that it can be retracted into and out of the through-hole provided in the pin guide member 60 formed with the rotary shaft 31 of the rotating plate 32 It is hinged to (60).

Accordingly, when the body 45 of the selection fitting pin member 40 is rotated about the hinge axis 46 within the allowable angle range, the body 45 is elastically supported by the spring 47 with respect to the body 45 at a predetermined interval. Four protruding pins 41 to 44, which are formed, enter and exit the through hole 61 formed in the pin guide member 60.

On the other hand, the rotary plate 32 has the penetration of the protruding pins 41 to 44 on the circular orbit corresponding to the advancing direction of each of the four protruding pins 41 to 44 about the rotary shaft 31 at the rotational position thereof. The through holes 32a are formed to be selectively controlled accordingly.

The interference switch is applied to a port interrupter (not shown) installed to block the optical path by the advancement of the protruding pins 41 to 44 that have passed through the rotating plate 32 in a non-contact manner in addition to the illustrated contact switches 51 to 54. You may be.

See the working relationship of this paper receiver.

First, the user takes out the paper storage case 21 from the main body 11 and loads paper in order to load paper having a size necessary for printing. Next, the control plate 22 is moved to regulate the paper outline such that the paper is aligned with respect to the side wall 21a of the paper storage case 21. At this time, the selection pin member 40 is made by the regulation plate 22 in the state in which the protruding pins 41 to 44 are adjusted to retreat with respect to the rotating plate (32). In this process, the rotating plate 32 is rotated from the initial position by an angle corresponding to the sheet restricting position of the regulating plate 22.

After the paper is regulated, if the handle of the body 45 is moved downward so that the selection pin member 40 can move the projection pins 41 to 44 with respect to the rotating plate 32, the projection pins 41 to Only the protruding pins 41 to 44 in which the through hole 32a is placed in the forward position among the 44 are penetrated through the rotating plate 32, and the rest is blocked. For example, in the case of the through-hole pattern shown in FIG. 5, when the paper size regulated by the restricting plate 22 is B5 paper, a line connecting the letter denoted by B5 and the rotating shaft 31 is the protruding pins 41 to 44. Side by side to the alignment position (T) of the () is completed so that the other protruding pins 42 to 44 except the first protruding pin 41 can be moved forward through the corresponding through holes (32b) (32c) (32d). . By the same principle, when the paper size regulated by the regulating plate 22 is A4 paper, only the third and fourth protruding pins 43 and 44 can be moved forward through the corresponding through holes 32e and 32f. In the case of B4 paper, only the fourth protruding pin 44 can be moved forward through the corresponding through hole 32g. According to this principle, there are 16 or more combination code signals that can be produced by selective penetration of the rotating plate 32 to the four protruding pins 41 to 44. Therefore, the through hole 32a is formed at the corresponding rotational position of the rotating plate 32 so as to generate a mechanical code signal by the selective advancement of each of the protruding pins 41 to 44 according to the paper size used in general. Correspondingly, an interference switch such as contact switches 51 to 54 may be provided on the main body 11 within an allowable advance distance of the protruding pins 41 to 44 so as to electrically reproduce the code signal.

When the paper storage case 21 is pushed to the mounting completion position inside the main body 11 while the contact switches 51 to 54 are provided inside the main body 11, the protruding pins 41 penetrating the rotating plate 32 To 44 interfere with the contact switches 51 to 54, so that the contact switches 51 to 54 output interference information due to the interference of the protruding pins 41 to 44 to the system controller (not shown). As a result, by the code signal of the predetermined interference switch, the system control device obtains the paper size information loaded by being regulated by the restriction plate in the paper storage case 21.

As described so far, according to the paper storage device of the printing press according to the present invention, the size information of the paper loaded in the paper storage case is provided in the system, so that users of remote printers connected through the display device or the communication network are provided. In addition to notifying the user of the size of the loaded paper, the system also allows proper control to suppress printing errors, such as stopping the print job when the size of the paper required for printing and the size of the paper loaded in the paper storage case do not match. Let's do it.
