ない欠点を有していた。However, the serial printer as described above has a drawback that it cannot continuously feed an arbitrary amount of paper and must repeat the same action intermittently when performing paper feeding or the like.
そこで本考案の目的は、従来のこのような欠点を解決す

送りローラを可能とするものである。In order to solve the above problems, the present invention provides a head feed having a groove having a lead angle of 0 ° provided at one end (initial setting position) and a spiral groove formed continuously from the groove for moving a head carrier. A screw, a paper feed clutch with which the head feed screw meshes after a constant rotation, and a paper feed roller to which power is transmitted via the paper feed clutch are configured to enable an arbitrary amount of paper feed roller. .

行うことができる。According to the above configuration, one cam that rotates when the head feed screw rotates and the other one that meshes with the paper feed roller.
A paper feed clutch having two cams is provided at one end of the head feed screw, and the head carrier performs a predetermined printing until the cam that rotates when the head feed screw rotates is engaged with the cam that engages with the paper feed roller. Since it is set so as to be maximally movable within the range by the head feed screw, the rotation of the head feed screw is not transmitted to the paper feed roller while the head carrier is conveyed in the printing direction. Further, when the head carrier is at the initial setting position of the lead angle of 0 ° formed on the head feed screw, the cams of the paper feed clutch are in mesh with each other. When rotated in the opposite direction, the cam that meshes with the paper feed roller is driven by the cam that is rotated by the head feed screw. The feed roller is rotated, this result, it is possible to perform any amount of paper feed in response to the rotation of the head feed screw.

きる。An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a motor 1 transmits power to a head feed screw 2 and a head feed pin 4 fitted in a head carrier 3.
Engages with a groove formed in the head feed screw 2 and moves the head carrier 3 in the axial direction along the groove. A groove having a lead angle of 0 ° as shown in FIG. 2 is formed at the final end of the groove of the head feed screw 2 which corresponds to the initial setting position. When the motor rotates in the reverse direction, the head carrier 3 is fitted to the head carrier 3 as shown in FIG. The head feed pin 4 has a structure capable of sliding in the radial direction of the head feed screw.
Power can be transmitted to the head feed screw 2 without moving.

ことが可能な構造となっている。Power is transmitted to the paper feed roller 5 from the head feed screw 2 via the paper feed clutch 6. The paper feed clutch 6
4 is composed of a plurality of cams 8, 9 and 10 as shown in FIG. 4, and has a structure capable of transmitting power after the head feed screw 2 rotates arbitrarily.

ができる。Next, the operation will be described. When power is transmitted from the motor 1 and the head feed screw 2 rotates in the forward direction, the head carrier 3
Moves from the initial setting position in the direction of arrow A and prints an arbitrary amount. At this time, the power of the head feed screw 2 is reduced by the speed reducer 7
4 is transmitted to the # 1 cam 8 shown in FIG. 4, the # 1 cam 8 rotates counterclockwise, and is transmitted to the # 2 cam 9 by the movement amount of the head carrier 3, but at the time of maximum movement of the head. It is not transmitted to the last n # cam 10. Therefore, when the head feed screw 2 rotates in the normal direction, the power is not transmitted to the paper feed roller 5. After the printing of an arbitrary amount, the motor 1 rotates in the reverse direction, the head feed screw 2 rotates in the reverse direction, and the head carrier 3 moves in the direction of arrow A.
Move in the direction. At this time, the power of the head feed screw 2 is transmitted to the 1 # cam 8 through the reduction gear 7, the 1 # cam 8 rotates clockwise, and when the head carrier 3 returns to the initial setting position, the 1 # cam 8, 2 # ready cam 9 and the final n # arm 10 is engaged further by reversing the arbitrarily motor corresponding to the paper feed amount, it is possible to perform the paper feeding any amount continuously.

ことができる。As described above, according to the present invention, when the head carrier is conveyed by the head feed screw for the printing operation, the paper feed clutch provided at one end of the head feed screw is not in the meshed state and therefore the paper feed roller is not engaged. When the head carrier is in the initial setting position of the head feed screw without rotating, the paper feed clutch is in a meshed state, so if the head feed screw is rotated in the direction opposite to the head carrier conveyance direction, The paper feed clutch can continuously rotate the paper feed roller by an arbitrary amount according to the rotation amount of the paper feed clutch. As a result, it is possible to provide a simple and low-cost printer such that paper can be fed by a desired amount.
