Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a carbon paper holding device in a typewriter machine.

[Conventional technology]

Conventionally, in the carbon paper holding device of this type of typewriter, the clamping force was applied by the magnetic force of a magnet (see Utility Model Application No. 59-83551) or by the elastic force of a spring. A structure is known in which carbon paper is held by a clamping plate that functions by the applied clamping force.

[The problem that the idea aims to solve]

In the conventional method described above, the sandwiching plate is held in a non-clamping state by resisting magnetic force or elastic force with the fingers of one hand, and the carbon paper is set in a predetermined position with the fingers of the other hand, and then both of the above are performed. The loading operation is complicated and difficult to use because it is necessary to load the carbon paper by releasing the cassette, and positioning the paper is difficult because loading the carbon paper into the specified position requires one hand. Not only is this undesirable, but it also has defects such as children often being unable to replace the carbon paper, requiring an adult to help each time, and the structure requires magnets or springs. However, it also required the installation of the magnet or spring, leading to increased costs.

The object of the present invention is to provide a new carbon paper holding device for a typewriter device that eliminates the above-mentioned defects.

[Means to solve the problem]

In order to achieve the above object, the carbon paper holding device in the typewriter toy according to the present invention uses a holding section in front of the paper wound around the platen to hold the carbon paper in a state away from the platen and the dial. In a typewriter toy in which the typeface of a dial is stamped on this carbon paper and the same typeface is transferred to the paper, the holding part of the carbon paper 26 is extended parallel to the platen 8 and directed upward. A deep groove 24 with an open bottom 24' is provided, and a large number of front guides 27 are provided on the inner surface of the front wall 25 of the deep groove 24 to push the lower edge of the carbon paper 26 inserted into the deep groove 24 toward the rear, Also, the lower edge of the carbon paper 26 inserted into the deep groove 24 is pushed forward by the front guide 27 on the inner surface of the rear wall 25' of the deep groove 24.

A carbon paper 26 cut into a strip and tied to the front surface of 8 is placed in the deep groove 24 for delivery.
Insert the carbon paper 26 in a horizontally long state, then stand the carbon paper 26 upright away from the platen 8 and the dial 75, and turn the dial 75 to open the window 95,
Make the character you want to type appear at 95'. If the character you wish to type is the typed character 73 on the upper row, press only the character input key 54 and move the back and forth vertically movable table 40 and the dial 75 on the same table 40 via the first actuating rod 47. Then, in the initial stage of the movement, the rear end of the first actuating rod 47 starts moving the second actuating rod 48 rearward via the overhanging part 59, and in the middle stage, this movement starts. As the second operating rod 48 continues to move, the upward protrusion 61 repositions the left-right moving table 5 and the platen 8 to a position advanced by one character, and in the latter stage, the second operating rod 48 continues to move. Twisted upward protrusion 6
1 maintains the left-right moving table 5 and platen 8 at the position that has advanced by one character above so that they do not move left and right, and in this maintained state, the upper part of the dial 75 (the character to be typed) 73 is printed on the carbon. Push out the paper 26 and place the typing paper 18 on the platen 8.
Then, the impression of the upper type type 73 is transferred to the typing paper 18 via the carbon paper 26 (in the case of transferring the upper type type 73, the lower type type 73' is preferably in the cylindrical shape of the platen 8). ), and after transferring the upper type character, the pressing operation applied to the character input key 54 is canceled by releasing the key 54, and the entire character is returned to the state before the pressing operation. return spring 8
7 and 88, and if the desired character is the type 73' in the lower row, press the up/down switching key 56 to move the back-and-forth up/down direction moving base 40 to the third operating rod 49. , through the inclined guide surface 67, the horizontal pin 45 and the hanging plate 44, and press down the character input key 54,
In this way, the horizontal pin 45 slides on the platform 68 and moves the platen 8 while keeping the vertically movable table 40 and the dial 75 on the table 40 raised.
During the movement, the first actuating rod 47, the second actuating rod 48, the upward protrusion 61, etc. function in the same manner as in the case of transferring the upper type characters 73, and the lower type characters 73' is transferred to the typing paper 18 via the carbon paper 26 (in the case of transferring the lower printed characters 73', the upper printed characters 73 are separated from the platen 8 and are not transferred). At the same time, after the lower type printing is transferred, the up/down switching key 56 and the character typing key 5 are pressed.
1 (if the next character to be typed is also a type in the lower row, you can keep the up/down switch key 56 pressed down) and move the entire body to the return springs 87, 8.
8 and 89, and if it is desired to advance the platen 8 from the beginning, press and release only the advance key 55, and then move the second actuating rod 48. The horizontal movement stage 5 can be advanced by moving the upward protrusion 61 to the adjacent guide groove 31 by the movement of the downward projection 62 through the guide hole 65. In order to further return the platen 8, the horizontal movement stage 5 can be moved. All you have to do is directly put your hand on it and push it back against the force of the push ball 22.

[Effect]

The carbon paper holding device in a typewriter toy shop according to the present invention uses a holding section to hold the carbon paper in front of the paper wound around the platen in a state away from the platen and the dial, and prints the typeface on the dial onto this carbon paper. In a typewriter toy that transfers the same type of characters onto the paper by striking, the carbon paper 26 is held in a deep groove 24 parallel to the platen 8, with a long bottom 24' opening upward. A large number of front guides 27 are provided on the inner surface of the front wall 25 of the deep groove 24 to push the lower edge of the carbon paper 26 inserted into the deep groove 24 toward the rear. A plurality of rear guides 28 are provided on the inner surface to push the lower edge of the carbon paper 26 inserted into the deep groove 24 forward at positions between the pushing points of the front guide 27, and the front guide 27 The inner edge and the inner edge of the rear guide 28 are characterized by having inclined edges 27 and 28' forming a V shape when viewed from the side, so that when loading the carbon paper 26, it is necessary to use both hands to load the carbon paper 26. The lower edge of the paper can be simply pushed from above between the front guide 27 and the rear guide 28 in the deep groove 24 and guided by the inclined edges 27' and 28'.
