Title: Foreign matter mixing preventing mechanism of passbook printer
Inventor: KAJITANI HIROSHI
IPC: B41J13/26
Filed: 1988-03-25
Abstract: PURPOSE:To prevent the falling of foreign matter into an apparatus without damaging operability at the setting time of a medium, by alternately arranging recessed groove for collecting foreign matter and medium guides each having a narrow width for guiding a medium in front of a medium sucking/discharge port. CONSTITUTION:Since the width (a) of each of foreign matter collecting grooves 1 is larger than the diameter of the largest coin 6, the coin 6 is not passed through each groove part in a state riding on two medium guides 2. Since the width (b) of the medium guide 2 is sufficiently narrow, almost all of the foreign matter advancing on the medium guide 2 also falls to the left and right grooves of the medium guide 2. When a medium is set to a suction/discharge port 4, the medium can be set without being caught by the groove 1 because of the presence of the medium guide. Therefore, foreign matter such is a coin 6, a clip or a stapling needle is prevented from falling in the apparatus without damaging the operability of the device at the setting time of the medium and the obstruction of the apparatus or trouble such as the loss of the coin 6 can be prevented.

Abstract: PURPOSE:To eliminate the reduction in effective area of a buried element as well as to increase the uniformity of the buried layer by a method wherein the end part of the upper layer of a buried part is removed by etching, and subsequently a semiconductor is manufactured by performing an epitaxial growing method. CONSTITUTION:After boron has been diffused, an oxide film 18 is formed. Then, the oxide film 18 is selectively removed by performing a photolithographic method. After the above-mentioned oxide removing process has been finished, a distorted part (part A) is removed by performing an etching process using the oxide film 18 as a mask. Then, the oxide film 18 is removed and lastly, an epitaxial growing method is performed. As a process wherein the end section of a buried part is removed is added in advance by performing an etching, no crystal defect generating at the end section of the buried part is present. Accordingly, the part shown by 24 corresponding to the gap of boron diffusion layers 21 is turned to an active effective area.
