Description of the invention: [Technical field to which the invention pertains] The present invention relates to a machine width adjuster, and more particularly to an automatic mechanism for a printer paper feed width adjuster. [Prior Art] Generally, the width adjuster in the paper feed cassette of the printer is mostly manually adjusted to achieve the purpose of clamping, but the manual adjustment method has some disadvantages, for example, the current mechanism is fixed by the rack. Adjuster, but there is a gap between the racks, which can't be effective. If the paper is tight, the paper will be skewed during the printing work, which will affect the print quality. The paper width detecting device and the paper width detecting method of the printing system disclosed in Taiwan Patent No. 1234520 are mobile blocking device sensing devices, so that the interrupter sensing devices are respectively blocked by the two interrupters, and the respective masks are recorded. The position where the breaker sensing device is interrupted by the two interrupters is defined as - the first position and the second position respectively; and the distance between the first position and the second position is calculated to obtain the paper Width value. The paper width detecting device disclosed in the Tsuen Wan Patent No. 1234642 obtains a digital signal by forming a path between each of the conductor portions and the corresponding wires, and accordingly generates a paper width value. The above two Taiwan patents disclose the detection of the paper width value and do not automatically adjust the width adjuster in the paper feed E to the position where the paper is jammed. SUMMARY OF THE INVENTION The present invention has been made in order to automatically move the printer tray width adjuster to the position 1330592 in which the paper is jammed. The main purpose of the present invention is to provide an automatic mechanism for the width adjustment of the printer tray, which can automatically adjust the paper width of the paper tray, and can avoid the error of manual adjustment, which can more accurately control the paper feeding. stability. Another object of the present invention is to provide an automatic mechanism for a printer tray width adjuster, which can feed back the width value of the paper to the printer, and further remind the user of the paper to be printed and the paper tray. The paper does not match. The automatic mechanism of the printer tray width adjuster of the invention comprises: a motor provided with a transmission shaft for outputting power; a transmission gear set coupled with a transmission shaft of the motor side, the crucible being driven by the motor; a screw 'couples with the transmission gear set, and is driven by the transmission gear set; a paper feed cassette is provided with a bottom plate and a side plate; the bottom plate is provided with a long slot extending from a side end to the side plate; the screw is disposed a width adjuster includes a movable unit coupled to a transmission unit; the movable unit is disposed on an upper side of the bottom plate; the transmission unit is provided with a neck portion and an engaging portion; the long slot is received The engaging portion is disposed under the bottom plate; the lower end of the engaging portion engages the screw, and the cymbal is driven by the screw to move along the long slot, thereby driving the width adjuster to move toward the side plate to clamp The position of the paper can automatically adjust the paper width of the paper tray, avoiding the error of manual adjustment, more precise control of the stability when entering the paper, and feeding back the width value of the paper to the printer. It can further remind the user that the paper to be printed does not match the paper in the tray. 6 1330592 Other objects and effects of the present invention will be described in detail with reference to the drawings and the embodiments hereinafter. [Embodiment] Please refer to Figures 1 and 2. The printer sheet feeder width adjuster automatic mechanism comprises a motor 11, a transmission gear set 20, a screw 30, a paper feed cassette 40 and a width adjuster 50. The motor 11 is for outputting power, and the drive shaft ill of the motor 11 is coupled to the first gear member 112'. The first worm 112 is engaged with the transmission gear set 20; the transmission gear set 20 is coupled to the screw member 30. The paper feed cassette 40 is provided with a bottom plate 41 and a side plate 42. The bottom plate 41 is provided with a long slot 43 extending from one end to the side plate 42; the screw 3 is placed below the long slot 43. As shown in FIG. 2, the width adjuster 5A includes a movable unit tongue-and-loop coupling-transmission unit 52; the upper side of the bottom plate 41 of the movable unit 51; the transmission unit is provided with a neck portion 521 and a merging portion 522; The slot 43 accommodates the neck portion 521. The merging portion 522 is placed on the bottom plate 41 τ, and the lower shaft stalk is swayed by her L43 movement; the unit 5 snail 53 is engaged with the frame portion 532 and the second portion 53v 笙^c〇i ^ ^ 接 邱 惠 惠 第 第 第 第 第 第 第 ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; - 爆 (4) The 5 编 is programmed, and the lower end is combined with the penetration hole 1330592 of the cymbal printed by the interlocking unit, and the disk sensor 70 and the paper sensor 80. Please refer to Figure 5. When the paper 1 is placed on the bottom plate 41 against the side plate 42, the detecting rod 81 is pressed by the paper and retracted into the penetration hole 411, and the paper sensor 80 can generate a sensing signal. When the controller 9 detects the sensing signal, it sends a control signal to rotate the motor 11, and drives the width adjuster 5 to move in the direction of the side plate 42. When the width adjuster 50 moves to touch the paper 1 When the position can no longer be moved, the screw 30 is subjected to a large resistance by the width adjuster 5, so that the motor 丨丨 increases its rotational twisting force and consumes more power; when the controller 90 detects that the motor 11 consumes more When the power message is sent, a signal is generated to control the motor 11 to stop rotating, so that the motor 丨丨 stops rotating. Therefore, when a sheet of paper 1 is placed on the bottom plate 41, the width adjuster 5 is automatically moved to a position where the sheet 1 is held. When the motor 11 drives the encoder disc 6 to rotate synchronously, the encoder disc sensor can sense the amount of rotation of the encoder disc 60; the controller 90 detects that the encoder disc sensor 70 senses the encoder disc. When the value of the rotation amount is 60, the width of the paper 1 即可 can be obtained by comparing with the pre-stored value, and the user can be further reminded by the audio-visual display device that the paper is currently placed in the tray 4〇〇. The specifications allow consumers to avoid printing on paper that is not the required size. The present invention also causes a button of an electrical controller 取代 to replace the paper sensor 80, and sends a control signal to rotate the motor 11, so that the width adjuster 50 automatically moves to a position where the paper 100 is clamped. The invention makes the printer E width adjustment 位 from the position of the moving paper to the position of the paper 9 1330592, can automatically adjust the paper width of the paper tray 'can avoid the error of manual adjustment, and can more accurately control the paper feeding time. The stability 'and the paper's width value is fed back to the printer, which further reminds the user that the paper to be printed does not match the paper in the tray. The above description is only for the embodiments of the present invention, and any modifications and variations of the present invention will be made by those skilled in the art, and are not intended to limit the scope of the invention. %
