Abstract

PURPOSE:To enable recording to be easily performed starting at a desired recording-starting position on a recording medium by a method wherein a first edge of an outer casing of a recorder which is parallel to a scanning direction is set in a recording direction, and the recording-starting position of the recording medium is matched to a recording-starting position set in the vicinity of an intersection of the first edge and a second edge of the casing substantially orthogonal to the first edge. CONSTITUTION:When a recording-starting switch 101 is depressed and scanning is manually started in the presence of recording data stored in a RAM 52, a pulse signal indicative of the rotation of a roller 102 is inputted through an input port 55. A CPU 50 detects the amount of rotation of the roller 102, based on the pulse signal, and after a hand printer 100 is moved scanningly by a predetermined blind feed amount, the CPU 50 outputs the recording data to a driver 54 synchronously with the pulse signal. A recording head 103 is driven according to the recording data, in synchronism with the scanning movement of the printer 100, thereby performing recording on a recording sheet.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a manual scanning type recording device that performs recording by manually scanning a recording medium.

[Prior Art] Conventionally, many printing devices such as inkjet printers, thermal printers, and wire dot printers have been on the market as printing devices for printing characters, images, etc. on recording paper or the like. However, due to the paper feed mechanism and the size of the device, printing with these printing devices is limited to printing single sheets of up to 84 size or thin booklets such as bank passbooks, etc. For example, printing in bookbinding is limited. It was not possible to print on thick books, documents, or large sheets of paper. Therefore, as a printing device that eliminates the limitations related to recording media due to the shape and paper feed mechanism of these devices, we have developed a handy printer that can manually scan the device body and print at any position on the recording sheet 1 like a writing instrument. is proposed.

When the start switch 101 is pressed in step S1, the process advances to step S2, and it is checked whether the recording data to be recorded is stored in RAMg2. If there is no recorded data, the process proceeds to step S3, and the process moves to error processing such as displaying an error message. If record data exists in step S2, the process advances to step S4 and waits for a pulse signal from the photosensor 106 to be input.

When the pulse signal is input, the process proceeds to step S5, and the amount of rotation of the roller 102 is determined based on the number of input pulse signals. Then, in step S6, this rotation amount is d/2πR(
(in the case of Figure 1). If this amount of rotation has not been reached, the process returns to step S4 and the above-mentioned operation is executed; however, if the amount of rotation has been reached, the process proceeds to step S, where the recording data is output to the driver 54 and the driver 10 is sent for recording.
